1 Introduction
This manual describes the Soekris Engineering net4501 Series of boards and systems. The net4501 is
available as a board only, or in a small sheet metal case. In both cases, they are available in different
configurations.
The net4501 is based on the ElanSC520 embedded processor from AMD, and is basically a PC compatible
embedded computer optimized for network and communication applications.
This manual assumes that the reader has a deep understanding of PC Architecture, and will only cover
areas specific to the net4501. Most of the net4501 functionality and interfaces are either following official
PC standards, or unofficial de-facto standards.

Bus Expansion
The net4501 has two different PCI expansion possibilities, the connector J2 is a standard 3.3V PCI v2.2
connector and J3 is a Mini-PCI type IIIA socket.
Please note that there is limited power available for the two PCI expansion connectors. There are only 3W
available on the 3.3V power pins, there is no power available on the +12V and –12V power pins. And
when using the DC Input Jack as the power source, only very limited amount of power is available on the
5V pins, as the 5V is then supplied by a linear regulator.
CAUTION: Please note that the Standard PCI connector is a 3.3V signaling only connector, and is
keyed for that. Do not insert a 5V PCI expansion board upside down, that can cause permanent damage
both to the net4501 and the expansion board.
3 BIOS
3.1
Overview
The net4501 comes with the Soekris Engineering netBIOS. The BIOS is designed especially for setup and
operation using the serial port as the console. The BIOS is located in Flash memory, and can be upgraded
over the serial port. Critical system setup parameters are also saved in the Flash memory, so the system will
not lose any setup information due to CMOS battery backup power loss.
3.2
Serial Console
The net4501 dops not have any video or keyboard interface, and uses the COM1 serial port for the primary
console interface instead. The serial port default baud rate is 19200, but it can be changed by the monitor
“set” command. The netBIOS also has an emulation of int10 video system calls and int16 keyboard system
calls, making it possible to run old real mode programs that expect video and keyboard services. This is
mostly useful for running MS-DOS, and is limited to software using the BIOS calls only. The serial port
connector is a standard PC type 9 pins D-SUB, so a serial crossover cable should be used when connecting
to an other PC.
3.3
System Startup
When the net4501 is powered up or rebooted, the netBIOS will first display diagnostic checkpoint codes on
the serial console. When it has located and checked the first 64 Kbytes of main memory, it will display a
sign on message and then continue with additional testing and configuration. After that, it will start a short
countdown before it will try to boot an operating system. During the countdown time, by pressing Ctrl-P,
the normal boot process can be interrupted and control transferred to the comBIOS’s monitor program. The
monitor is a command line driven program for setup and light diagnostic and debugging. Typing “?” or
“help” at the command prompt will show a short list of commands available.
Note that after changing system parametes using the “set” command, it will be necessary to restart the
system before the new parameters will be used, by using the “reboot” command.
3.4
Monitor Commands
boot [drive]
Load operating system from a boot device, using int19 system call. Drive can either be a valid int13 drive
entered as a hexadecimal number, or a special number. For example “80” will be first fixed disk drive,
normally the CompactFlash on the net4501, and that is also the default if no parameter is entered. Currently
defined special number is “F0”, which will try to boot over the network, using the PXE boot ROM.
reboot
Will reboot the BIOS, normally used after changing system parameters.
download
Start downloading a binary image over the serial ports, using the XMODEM protocol. After entering the
command, start sending at the terminal program at the other end. Will time out after 30 seconds if it does
not detect the start of a XMODEM transfer. Downloaded binary image will be saved in memory at
4000:0000.
flashupdate
Update the system flash BIOS with image at 4000:0000, normally the one just downloaded using the
“download” command.
time [HH:MM:SS]
Update the time in the battery backed Real Time Clock, or if no parameter, show the current date and time.
The time should be entered in 24 hours format, as “hour:minutes:seconds”.
date [YYYY/MM/DD]
Update the date in the battery backed Real time Clock, or if no parameter, show the current date and time.
The date should be entered as “year/months/date”.
set parameter=value
Set a BIOS system parameter to a value. See section 3.4 for a list of currently available parameters to set.
Note that a reboot is required after changing most parameters before the new value will be used.
show [parameter]
Show the current value of a parameter, or if no parameter, show a list of all parametes and their current
value.
d[b|w|d] [adr]
List the content of the memory, in both ascii and hexadecimal. “db” will show it as 8 bit bytes, “dw” will
show it as 16 bit words and “dd” will show it as 32 bit doublewords. “adr” is a memory address in
hexadecimal, either in 16 bit seg:offset format or as a single linear 32 bit address. If no address is entered, it
will continue listing from last address, if “d” is entered alone, it will list in the last used format.
i[b|w|d] port
Input and show the content of a port address. “ib” will input a 8 bit byte, “iw” will input a 16 bit word and
“id” will input a 32 bit double word. The port address is in hexadecimal from 0 to FFFF.
o[b|w|d] port value
Output a value to a port address. “ob” will output a 8 bit byte, “ow” will output a 16 bit word and “od” will
output a 32 bit double word. The port address is in hexadecimal from 0 to FFFF, and the value is a
hexadecimal number.
e addr byte [...]
Enter values in memory. “adr” is a memory address in hexadecimal, either in 16 bit seg:offset format or as
a single linear 32 bit address. “value” is one or more 8 bit bytes.
3.5
BIOS System Parameters
ConSpeed
Serial Console speed baud rate. Value can be 2400, 4800, 9600, 19200, 38400 or 57600, default is 19200.
ConLock
Protecting the serial console port from modifications using int14 system calls. Value can be “enabled” or
“disabled”, default is “enabled”. Useful for preventing MS-DOS from changing the console speed on start
up.
BIOSentry
To control if the “Press Ctrl-P for entering Monitor.” message should be displayed during before booting.
Value can be “enabled” or “Disabled”, default is “enabled”. Useful for making it harder for end users to
enter the monitor and modify BIOS settings. Note that pressing “Ctrl-P” will still work for entering the
monitor.
PCIROMS
To control if the BIOS will execute code found in PCI expansion ROM’s. Value can be “enabled” or
“disabled”, default is “enabled”. Can be used to disable problematic ROM’s on PCI boards, or to shorten
the BIOS boot time.
FLASH
To set the disk channel of the onboard CompactFlash socket. Value can be “primary” or “secondary”,
default is “primary”. Useful if the system is used with an external IDE controller.
BootDelay
To set the delay time before booting an operating system. Value can be from 2 to 16 seconds, default is 5
seconds.

4.14 D10, Power On LED
This green LED will be on when there is applied power to the board.
5 Software Installation
The net4501 is designed to be fully PC compatible, but has some limitation due to the design decision to
leave out the video, keyboard, floppy and IDE interfaces.
5.1
CompactFlash use
The CompactFlash socket is the only medium for permanent program and data storage. There are two ways
of loading software on the CompactFlash card.
•
Booting an install program using the PXE boot ROM, and then installing the rest over the network.
Only some operating systems support PXE booting and/or installation over the network.
•
Preloading the CompactFlash card on another system. As the CompactFlash emulates an IDE device, it
can be connected to a host system using either an IDE-CompactFlash adapter, a PCMCIA to
CompactFlash adapter or a USB based reader/writer. Differences in sector translation using IDE
devices can complicate doing the loading on another system. The net4501 uses a simple algorithm for
sector translation, if there are less than 1024 tracks, it will use the native CHS that the CompactFlash
reports, if more than 1024 tracks, it will use LBA translation. So the host system will need to match
that, and that will also normally be the case. In some cases it may be necessary to change the
translation settings in the host system’s BIOS.
5.2
Ethernet Drivers
The used DP83815 ethernet controller is directly supported by the newer versions of most operating
systems, and will normally be automatically detected. As it is a relatively new chip, it may be necessary to
upgrade to the newest version, or to locate device drivers. For most operating systems, drivers are available
on National Semiconductors website at http://www.national.com
